HENRY MAYER, OF NEW YORK, N. Y.

APPARATUS FOR PROJECTING PICTURES DURING PRODUCTION.

Specification of Letters Patent- Patented Aug. 20,1912- I Applicationfiled November\3, 1911. Serial No. 658,354.

To all whom it may concern:

Be it known that I, HENRY MAYER, a citizen of the United States, and aresident of the city of New York, borough of Ma'nhat-' tan, county andState of New York, have invented certain new and useful Improvements inApparatus for Projecting Pictures During Production, of which thefollowing is a full, clear, and exact description.

This invention relates to certain improvements in the projecting ofpictures on to screens during the process of producing the picture .andin sucha manner as to show the hand and drawing instruments on anenlarged scale, making their necessary movements in producing thepicture.

My invent-ion is particularly useful in entertaining an audience or inillustrating or in teaching to them the art of drawing, sketching orpainting. The apparatus is so constructed that not only the picture butalso the hand and drawing instruments appear in all their naturalcolors, so that an audience or class may see what seems to be agiganticihand, appear on the screen, pick up the pencihpen or brush andproceed to sketch or paint the picture. The-parts are not shown merelyin relief, but appear in natural colors in all respects.-

Reference is to be had to the accompanying drawings,. which form a partof this specification and in which similar reference characters indicatecorresponding parts in the different views.

Figure 1 is a perspective view of an apparatus constructed in accordancewith my invention, .a portion of the casing being broken'away; Fig. 2 isa central longitudinal section; and Fig. 3 is a transversesec- Myimproved apparatus'involves a casing 10 of suitable material, which issubstantially fireproof and lightproof and sufficiently light to permitof its ready transportation; The casing is supported in any suitablemanner as, for instance, upon legs 11 and at such a'height that a personstand ing or sitting may insert his hands into the casing. The casinghas'a bottom or floor 12 upon which may be supported a drawing board andpad or a sheet of paper or canvas 13 or any suitable surface upon whichthe drawing or picture may be produced.

To enable the operator to gain access to the casing without admittinglight, the easinglhas an opening 14 at one end with a fabric sleeve 15connected thereto, so that the operator or artist may extend his handinto the sleeve and gather the outer end of the latter tightly about hisarm. This opening 14 permits the insertionof the right hand and on anadjacent side has an 'openin 16 covered by a depending heavyflap 1 ofopaque fabric and throu h which the fingers or a portion of the le thand may be-insorted to hold the paper stationary or to adjust thepencils, pens, paint cups or the like. The flap falls down from the end,so that practically no light can escape from the cabinet to eitheropenings 14 or 16.

Within the cabinet and at the end having the opening 14 is an inclined,mirror 18 preferably hinged and supported by an adjustable rod 19, sothat its inclination may be varied. At the end of the casing opposite tothe mirror 18 is anysuitab'le means for producing an extremely highdegree of illumination within the'casing. As a practical device forsecuring this result, I employ an are light mounted. in a separatecasing 20 and having the carbons 21 so.

positioned that the intense light'produced may be projected through alens 22 on to the mirror 18 and thus down onto the paper upon which theartist is producing the picture. The casing 20.of the are light issubstantially lightproof, although it may have ventilating openings inthe upper end. I do not claim any improvementz'whatsoever' in the arelight and have not illustrated any of the details of wiring, adjustmentof car bons or any other features essential to are lights. It is, ofcourse, understood that thenecessary details of this part can be readilyproduced by any electrician familiar with electro-arc lights.

In order to enable the artist, to see what he is producing upon thepaper orcanvas 13, I provide a window 23 in' the side of the casingdirectly above the opening 16. This window is formed of one or morethicknesses of coloredglass, the' color and thick- {ordinarily would.

nessfbeing such that they will protect the eyes of the artist from theextremely'high illumination or glare'within the casing and at the sametime will not permit the illumination of .objects outside of the casingif the device .be used in a dark room, as it In order to obtain the besteflect, the paper 13 is illuminated by the intense white light, but thislight is retained within the casing by reason of a sleeve 15, the flap 17 and-the colored window 23, except that part which is projected on tothe screen. The apparatus may be used in connection with any suitableform of screen, but I have v illustrated a screen 24 of any suit-ablematerial and eit er opaque or translucent. If

the screen be opaque, then the picture would be projected on tothe sameside as that viewed by the audi'ence,.while 'with a translucent screenan'apparatus may be on one side and the au ience on the other. Forprojecting the picture on to the screen, the

jdrawing instruments come directly below the. tube, so that the viewwhich is thrown top wall 25 oft-he casing is provided with a verticaltube including two telescoping sections 26 and 27 and within thesesections are the proper lenses which will throw an image of the pictureon to amirror 28 supported above the top of the tube. This mirror issupported in any suit-able manner and is'inclined at approximatelydegrees to the horizontal, s othat the image which is thrown directly?upward from-the paper 13' 'will-be reflected substantially-at rightangles against the screen. The hand, paper and ien'to'the screen is 'atop plan view of whatever is placed onthe bottom -of the casing. Thisincludes not only the hand, paper and drawing instruments, but'a-lsoinkwells, oil

I v; pontents of the casing being with a bright, white light, thepicture which tubes, paint cups, crayons and the like. The illuminatedis reflected on the image is in all the natural colorsof the objectitself, though ona much attachments or refinements-'which do not gotOJ'Jhe essence of the invention. For instance the top wall of thecasing may be provided with ventilating openings 29 to reduce the hightemperature within the easing and the end'wall may be provided with dapivotally supported mirror 30 in which the artist may look to see whatis shown on the screen. The upper section of the tube may be adjustedvertically in any suitable manner to vary the focusof the picture.

Various changes may. be made in-the construction of the deviceillustrated without departing from the spirit of my invention.

Having thus described my invention, what I- claim as new and desire-tosecure by LettersPatentis:'
